Sažetak
Among the large family of metal organic frameworks (MOFs), highly stable Zr-based MOFs are one of the most interesting members with various application areas owing to their stability, high porosity, high density of metal centres included in the cluster nodes, and varied types of topologies. However, the conventional synthetic method of pure phase polymorphs is still a challenge. Herein we present rapid, clean, high-yield mechanochemical synthesis of pure phase cubic MOF-525 and hexagonal PCN-223 polymorphs built on tetratopic porphyrin linker by liquid-assisted grinding technique.[1] In-situ powder X-ray diffraction monitoring performed at the DESY synchrotron source reveals that particular ball-milling conditions can induce the transformation from cubic to hexagonal phase, denoting MOF-525 to be a kinetic phase in this polymorphic system. Electron spin resonance (ESR) data of these polymorphic MOFs showed significant differences due to the different spatial arrangement and efficient separation of the metal centres (Cu(II), Mn(II) and Fe(III)) in the porphyrin rings, denoting them also as candidates for advanced spintronics applications.
